'Fools' in the Bible

“For My people are fools;they do not know Me.They are foolish children,without understanding.They are skilled in doing what is evil,but they do not know how to do what is good.”

I thought, "Surely it is only the ignorant poor who act this way. They act like fools because they do not know what the Lord demands. They do not know what their God requires of them.

A sword against the diviners. They'll be made fools. A sword against her warriors. They'll be shattered.
